Latest Patents

One of his latest patents is titled "Method for controlling transmission control clutches." This invention outlines a system and method for managing the clutches in a vehicle powershift transmission. The control system utilizes a microprocessor that periodically executes an algorithm, storing a sequential set of time reference values and pressure values in its memory. It applies unique fill pressure pulses to each oncoming element for specific fill periods. Additionally, the system determines shift time values based on the fill period and applies pressure signals accordingly. Another significant patent is the "Calibration method for transmission control clutches." This method involves calibrating the fill pressures of hydraulically operated brake and clutch elements by disconnecting the transmission output shaft from the vehicle drive shaft. The engine runs at a predetermined speed while the calibration pressure is gradually increased, allowing for precise adjustments.
